Description

A digital education system that controls multiple class tabs on student terminals from a teacher terminal.

[0001] The present invention relates to an educational system that, when one or more digital materials are transmitted from a teacher's terminal to a student's terminal screen, configures multiple class window tabs on the student's terminal screen based on the transmitted information and controls the class window tabs on the student's terminal screen from the teacher's terminal. More specifically, the invention relates to a system in which, during a class at school, multiple URLs necessary for a digital class are transmitted from the teacher's terminal either at once or one by one to create one or multiple class window tabs on the student's terminal screen using the transmitted information, and the created class window tabs are controlled from the teacher's terminal according to the class content to enable the digital class to proceed easily and quickly. Furthermore, the invention relates to a system in which, if a teacher who may experience difficulties with digital classes uses the system according to the present invention, the teacher can also conduct digital classes easily, quickly, and efficiently.

[0002] With the development of the information industry, IT education is being placed great importance on the school curriculum. In particular, due to industrial advancements such as artificial intelligence, there is an urgent need for digital education, and classes are being conducted using devices such as laptops and tablets with digital textbooks as teaching materials.

[0003] When conducting digital classes using devices such as laptops and tablets, teachers are sharing digital materials with students using various teaching support programs installed and operated at the school, or conducting classes using web digital platforms created using Google’s WRTC (Web Real Time Communication) technology.

[0004] The aforementioned class support programs include Net Support School and U-Class, which utilize mirroring and edutech technologies, and various web platforms such as Focus Pang, Hi Learning, DooClass, Codle, and iTalkTalk have been developed.

[0005] Products similar to Net Support School and uClass described in the above class support program help students conduct digital classes by transmitting digital information to student terminals through methods such as sending files and sending URLs.

[0006] Web platforms such as the aforementioned HiLearning, Focus Pang, DoClass, Codel, and iTalkTalk establish various learning environments on web servers, which are a characteristic of web platforms. Currently, students utilize their personal information to log in to the web server and conduct various digital classes using lesson content designed by the teacher.

[0007] Products such as NetSupport School and uClass utilize technologies like file sharing, URL transmission, and student monitoring for digital classes, allowing teachers to transmit their digital materials and the vast amount of digital information available on the web to students, enabling them to directly use these materials for instruction. However, since classes must be conducted at the students' discretion, there is an increasing risk of exposure to harmful digital materials. Furthermore, digital materials transmitted by teachers often require operation using general programs installed on student devices, such as web browsers, PowerPoint, or Photoshop; consequently, the issue of program installation also presents a challenge in the digital learning environment. Additionally, given the diverse nature of class content, it is necessary to conduct video and web-based lessons related to PDF textbooks simultaneously during class time; however, since such an environment has not been established, there is a problem requiring the continuous request and transmission of necessary digital materials.

[0008] Unlike the class support program, the web platform described above is very well designed and operated to enable digital classes tailored to the current educational situation. However, upon examining this web platform, classes are designed specifically for digital learning, and students proceed with these digital classes by undergoing a complex login process involving their personal information.

[0009] In addition, when a teacher conducts a lesson using PDF textbooks, students can participate in the class alongside the teacher through their device screens; however, there is a problem in that students can bypass the PDF lesson and access a different website to exit the class environment.

[0010] This is because classes must be conducted in a web browser, but since there are various tabs in the web browser, there is a serious problem in that students can leave the class by switching to another browser tab whenever they want.

[0011] In this case, while it is possible to monitor the student's screen, this is only possible if the student is engaged in the lesson being conducted by the teacher; if the student is surfing the web through another tab in the web browser, monitoring becomes impossible. All web platforms share this same problem.

[0012] The objective of the present invention, which aims to solve the aforementioned problems, is to establish a digital learning environment that is easy, fast, and diverse for difficult digital classes. Specifically, it aims to establish a learning environment on the student screen using a class window tab based on the transmitted information when various digital materials, such as URLs, PDFs, and videos that the teacher possesses or that exist on the web, are transmitted from the teacher's terminal to the student's terminal.

[0013] In addition, the purpose is to enable students to focus on the lesson by allowing the teacher to control the established class window tab while conducting the lesson.

[0052] The technical configuration of the present invention and the resulting effects will be more clearly understood when explained in reference to the drawings attached to the specification of the present invention. Hereinafter, an educational system for conducting classes by transmitting various digital data through a composite digital transmission unit according to an embodiment of the present invention and displaying multiple class window tabs on a student terminal will be described in detail with reference to the attached drawings.

[0053] However, in describing preferred embodiments of the present invention in detail, if it is determined that a specific description of related known functions or configurations could unnecessarily obscure the essence of the present invention, such detailed description is omitted.

[0054] Additionally, throughout the specification, when it is said that one part is 'connected' to another part, this includes not only cases where they are 'directly connected,' but also cases where they are 'indirectly connected' with other components in between.

[0055] The described embodiments are provided to enable those skilled in the art to easily understand the technical concept of the present invention, and the present invention is not limited thereby. Furthermore, the details indicated in the attached drawings are schematic drawings intended to easily explain the embodiments of the present invention and may differ from the actual implemented form.

[0056] Meanwhile, the expression 'includes' certain components is an 'open-ended expression' that merely refers to the existence of the components in question and should not be understood as excluding additional components.

[0057] Additionally, terms such as 'first, second, third, fourth, etc.' may be used to describe various components, but these terms are used solely for the purpose of distinguishing one component from other components, and the attributes of said components are not limited by said terms.

[0058] In the present invention, the term "first program for a teacher terminal" refers to a type of platform for a teacher terminal that is installed on a teacher terminal and controls a student terminal, and the term "second program for a student terminal" refers to a type of platform for a student terminal that is installed on a student terminal and corresponds to the first program installed on the teacher terminal, and the term "third program" refers to various tool programs such as Entry, Word, and PowerPoint that are installed on the teacher terminal and the student terminal.

[0059] In the present invention, 'class mode' refers to a mode in which a class is conducted by distributing content selected by the teacher to be taught to student terminals during class time.

[0060] In the present invention, "programs that interfere with class mode" refers to programs that interfere with class by executing programs such as games, Word, Excel, a first internet browser, YouTube, etc., other than the class content provided by the educational screen distribution unit during class time.

[0061] In the present invention, the term "first internet browser" refers to internet information displayed on the screen of a student terminal through various internet browsers, such as Chrome, Edge, and Whale browsers, which operate generally outside of the second program for the student terminal of the student terminal; that is, it refers to the internet executed through a commonly used internet browser. In this case, there may be multiple internet browsers commonly used, such as Chrome, MS Edge, and MS Explorer.

[0062] In the present invention, the term "second internet browser" refers to a specific internet that is executed within the first program for the teacher terminal of the teacher terminal and the second program for the student terminal of the student terminal, and which is displayed in the second internet information display area of ​​the second program for the student terminal of the student terminal when a specific browser created separately from the first internet browsers is executed and an internet address, which is internet information, is distributed from the teacher terminal to the student terminal.

[0063] In the present invention, the “class window” refers to a specific browser created separately that can display various digital materials, unlike the first internet browser, in the first program for the teacher terminal and the second program for the student terminal, and is configured with various class window tabs (60).

[0064] The above 'class window tab (60)' is configured to display various digital class materials in the first program (30) for the teacher's terminal and the second program (31) for the student's terminal, so digital materials such as PDF materials, video materials, internet materials (URL), AI courseware, AI platform, digital textbook, Hangul, Excel, Photoshop, AutoCAD, etc., can be configured into various class window tabs (60).

[0065] The above “class window tab” can be configured in various forms, for example, the class window tab can be configured as a left-right swipeable form or as a class window tab that scrolls up and down. In addition, depending on the case, it can be configured as a form where no tab exists.

[0066] In the present invention, the 'class window tab management unit (40)' is configured in the first program (30) for the teacher terminal and the second program (31) for the student terminal, respectively, and the class window tab management unit (40) configured in the teacher terminal plays the role of managing and controlling various class window tabs displayed on the student terminal.

[0067] The class window tab management unit (40) configured in the second program for the student terminal above serves to manage and control each class window tab displayed on the student terminal, and in the present invention, the composite digital transmission unit (33) is configured in the first program (10) for the teacher terminal, and may be configured separately from the class window tab management unit (40) or may be configured within the class window tab management unit (40).

[0068] Hereinafter, with reference to the attached drawings, embodiments of an educational system for conducting classes according to the present invention will be examined in detail.

[0069] FIGS. 1 and 2 are block diagrams of a digital education system configuration in which a teacher terminal controls a plurality of class window tabs of a student terminal according to an embodiment of the present invention, and FIG. 3 is a screen diagram designed so that when a specific class window tab is selected from a plurality of class window tabs according to an embodiment of the present invention, the corresponding class window appears. Typically, in a classroom environment, a class is conducted with the first program (30) for the teacher terminal, i.e., the platform of the present invention, installed on the laptop, which is the teacher terminal (10), and the second program (31) for the student terminal, which is the platform, installed on the laptop or tablet, which is the student terminal (20).

[0070] At this time, before the class begins, if various digital materials are distributed from the teacher's terminal to the student's terminal through the complex digital transmission unit (33), a new class screen is created in the class window. At this time, the student proceeds with the class using the distributed class screen, and the class content provides a class environment consisting of various class window tabs (60), such as video material class, PDF material class, internet material class, program material class, AI courseware material class, digital textbook material class.

[0071] When looking at products other than the class window tab environment according to the present invention, they are generally referred to as mirroring software or edutech software. These software programs are traditionally mirroring-based class support programs that transmit a teacher program to a student screen, allowing the student to view the teacher's screen in real time while teaching, thereby sharing the screen of the teacher teaching with the students to conduct the class.

[0072] While this method allows for similar instruction on the web platform Hi-Learning, it presents a problem in that it is difficult to combine with other digital classes due to the one-way nature of the teaching method.

[0073] For example, when a teacher conducts a class by displaying a PDF textbook to students via screen mirroring, students are limited to viewing the PDF. In this situation, if a teacher intends to conduct a video lesson while viewing the PDF, the mirrored PDF lesson must be terminated and the video lesson must be mirrored back to the students, presenting a problem. This teaching method disrupts the flow of the lesson and is emerging as a issue that hinders the students' digital learning environment.

[0074] The composite digital transmission unit (33) configured in the first program for the teacher terminal above transmits various digital materials to the student terminal (20) in order to solve the above problems, and the class window tab management unit (40) of the student terminal creates and displays various class window tabs (60) in the class window of the student terminal.

[0075] When the class window tab configured in the student terminal transmits mirroring digital data and video digital data from the composite digital transmission unit (33), the class window tab management unit (40) of the student terminal configures a class window tab including a mirroring function and a video class window tab to enable mirroring classes and video classes simultaneously, and allows the student to proceed with the class by selecting the video class window tab without interrupting the PDF class being conducted in the mirroring class.

[0076] To solve the above problems, the first program (30) for the teacher terminal includes a composite digital transmission unit (33) configured to transmit various digital materials; and a class window tab management unit (40) that analyzes information received from the composite digital transmission unit and creates and displays class window tabs according to the digital materials of the class window.

[0077] Figure 4 shows a Chrome browser operating on a teacher's terminal and a student's terminal regardless of the present invention, and its function is the same as any browser such as Samsung Browser or Whale Browser, allowing the user to use the internet by selecting the corresponding tab.

[0078] In the browser of Fig. 4 above, it is suitable for digital classes utilizing the internet, and many users conduct classes using the Chrome browser. For example, voice and video can be transmitted by utilizing the WEBRTC technology of the Chrome browser, and a project can be configured in which the teacher's terminal and the student's terminal can communicate by utilizing this technology in all browsers.

[0079] However, despite knowing that this teaching method reliant on the Chrome browser has some limitations for digital classes—as closing the browser or switching tabs during class is tantamount to ending the lesson—it is currently being developed and introduced across various web platforms.

[0080] FIG. 5 is a screen diagram showing that when various digital materials are transmitted in a composite digital transmission unit according to an embodiment of the present invention, the class window tab management unit (40) of the student terminal analyzes the received various digital materials and creates and displays a class window tab suitable for the digital materials, and is characterized by creating and displaying a class window tab (61) that can run the corresponding PowerPoint if the digital materials are PowerPoint.

[0091] As an example of an embodiment of the present invention, the first program for a teacher terminal (30) is installed on a teacher terminal (10) and controls a student terminal; and the second program for a student terminal (31) is installed on a student terminal (20) and corresponds to the first program for a teacher terminal (30); wherein the first program for a teacher terminal (30) further includes a composite digital transmission unit (33) that transmits various digital materials to the student terminal in order to create and display a class window tab in the class window of the student terminal.

[0092] The second program (31) for the student terminal above is characterized by further including a class window tab management unit (40) that receives various digital data from the composite digital transmission unit (33) of the first program (30) for the teacher terminal above, analyzes the various digital data, and creates and displays a class window tab (60) corresponding to each digital data in the class window.

[0093] In addition, the present invention further includes a class window tab restoration unit (40d) configured in the class window tab management unit (40) of the second program (31) for the student terminal, which restores the class window tab environment identical to the existing class window tab when the student terminal is rebooted, the second program for the student terminal is terminated and re-executed, or the second program for the student terminal (31) is re-executed when an error occurs in the student terminal, when one or more class window tabs (60) are created and displayed in the class window of each student terminal.

[0094] In addition, the present invention is characterized in that the educational screen in which the class window tab was displayed after being downloaded by the class window tab restoration unit (40d) is restored to the student terminal screen, such that the number of tabs and tab contents prior to the download, the class progress content of the educational screen, the explanatory material content, the tool content, and the video explanation content are restored identically and displayed on the student terminal screen.

[0095] According to Japanese Patent Publication No. JP 2002-123399, when implementing an educational support system in computer classrooms such as elementary schools, a server computer is installed and connected to student computers via LAN. Data storage locations for each user are also placed on the server computer, allowing for use in the same environment from any student computer. Information regarding the user environment used by the user is read from an electrical storage means and restored through a predetermined operation by the user at the location. The information regarding the user environment is determined by the application program used by each user, and the information regarding the user environment is described as information intended to reproduce the screen used by each user. Japanese Patent Publication No. JP 2002-123399 describes a web-based method in which a component called a server stores and retrieves data such as individual or usage records in real time, which is a widely used traditional restoration method. Furthermore, for programs like Hangul or Excel, creating and saving specific data and then opening the saved file later also constitutes restoration.

[0096] However, unlike programs that utilize a restoration system that saves after recording, such as Hangul and Excel, as described in Japanese Patent Publication No. JP 2002-123399, the class window tab restoration unit (40d) according to the present invention restores the class window tab, and does not have a component called a web server, nor does it perform the function of transmitting information in real time through a LAN environment, and does not restore information by connecting to a server, but rather creates a class window tab from the class environment received from the teacher, and if the user does not remove the tab currently in use, the class window tab environment received from the teacher is saved as is on the student terminal, so that when the terminal is rebooted, or when a program for conducting classes through the class window tab is terminated or a problem occurs, the class window tab is restored and maintained to the saved existing class environment.

[0097] For example, if a teacher conducts a class for 30 students in a school classroom and sends class tabs A, B, and C to all 30 students, and class tabs A, B, and C are displayed on the screens of all 30 students' devices, but a specific student's device is turned off, it becomes impossible to conduct the class through any one of the class tabs A, B, or C when the student's device is rebooted because class tabs A, B, and C are no longer present. Therefore, the environment of class tabs A, B, and C is restored exactly as it is when the device is rebooted.

[0098] In addition, the class window tab restoration unit (40d) of the present invention updates the respective class window tab information in real time when a class window tab (60) is created and displayed or when a class window tab is deleted.

[0099] Looking at Japanese Patent Publication No. JP 2002-123399, the work state storage unit 14 describes storing all currently open screens and information for restoring these screens in the user environment information when the work state is saved from the command interpretation unit 12. However, the work state saving is the same as saving and managing individual work information such as Hangul, Excel, etc., and is completely different from the present invention.

[0100] The class window tab information generated in real time can be transmitted to and managed by the first program (30) for the teacher terminal through the class window tab management unit (40).

[0101] In addition, the present invention further includes a class window tab duplication check unit (40c) configured in the second program (31) for the student terminal and receiving various digital class information from the composite digital transmission unit (33) of the first program (30) for the teacher terminal, which checks for duplication and prevents duplicate class window tabs from being created; wherein the class window tab duplication check unit (40c) prevents the creation of duplicate class window tabs when a number of class window tabs are created in the class window of the student terminal, and when the teacher retransmits various digital materials or transmits new digital materials, if a class window tab corresponding to the same digital class is already created in the student terminal, the retransmitting or new digital materials are not created or are not displayed.

[0102] In addition, the present invention is characterized by further including a class window tab sync unit (40l) configured in the second program (31) for the student terminal, wherein a class window tab (60) corresponding to digital class information received from the composite digital transmission unit (33) of the first program (30) for the teacher terminal is configured in the class window, and when a class is to be conducted using the configured class window tab (60), if the class window tab to be taught is not distributed to some student terminals, disappears from a specific student terminal, or is terminated by a specific user, the teacher does not redistribute the class content to be taught, and displays a class window tab identical to the class window tab created and displayed in the class window of another student terminal on the student terminal where the class window tab (60) to be taught is not distributed to some student terminals, has disappeared from a specific student terminal, or has been terminated by a specific user.

[0103] If we look at Korean Patent Publication No. 10-2025-0016787 filed by the present applicant, it is described as detecting whether an educational screen has been arbitrarily terminated on some student terminal screens among a number of student terminals (00570), and if the educational screen has been arbitrarily terminated, redistributing the configuration of the educational screen on the teacher terminal, and redistributing content including files and rules corresponding to the educational screen only to the student terminals that have been terminated ((0056), (0248)).

[0104] Looking at Japanese Patent Publication No. JP 2002-123399, it is described as reading and restoring information of a user environment that the user was using from an electrical memory means by a predetermined operation by the user of the place, and the information of the user environment is determined by the application program that each user was using, and the information of the user environment is information for reproducing the screen that each user was using ((0008)). Korean Patent Publication No. 10-2025-0016787 is characterized by redistributing an educational screen, and Japanese Patent Publication No. JP 2002-123399 is about reading and restoring a stored memory.

[0105] Korean Patent Publication No. 10-2025-0016787 involves redistributing an educational screen, but this may result in a situation where it is impossible to determine which part of the rules in which the educational screen was initially distributed has a problem, i.e., if a problem has arisen with a specific student's educational screen.

[0106] For example, there may be cases where the distribution of the educational screen fails due to network issues, or cases where the distribution succeeds but the classroom environment cannot be set up for a specific reason. However, teachers are unaware of these problems, and since they cannot know that there is an issue with the classroom environment unless a student directly reports it, it may be impossible for the teacher to redistribute the educational screen.

[0107] Japanese Patent Publication No. JP 2002-123399 describes a method of reading and restoring a stored memory means, which applies only when logging into a server. This can be viewed as equivalent to being able to retrieve and use stored data when running a saved file again while using programs such as Hangul or Excel. In other words, the user must log in or retrieve a saved file to restore it.

[0108] In a school environment, since the teacher transmits the class environment for use rather than retrieving saved data upon login, students do not have to log in every time to retrieve the class environment. To perform the login process, approximately 30 students must participate in the class without exception, but there is a problem in that a significant amount of time must be consumed to restore the class environment identically for all users.

[0109] In order to solve these problems, the class window tab sync unit (40l) of the present invention automatically maintains the class window environment of the student terminal as is when the teacher proceeds with the procedure to conduct the class, regardless of whether a problem occurs in the student class environment or not.

[0110] In addition, when a teacher taps a specific class window tab among multiple class window tabs (60) to conduct a class, the class window tab sync unit, which operates automatically when the tab is tapped, is called once more when the tab is tapped to automatically sync the class environment between the students.

[0111] To explain the above-mentioned class window tab sync unit, for example, when a class is being conducted using a PDF digital class window tab, a video digital class window tab, and an AI coursewear Tinkerbell class window tab, if the video digital class window tab closes due to an internal error or if a student terminates the class window tab, the student must request the corresponding video digital material from the teacher again and receive the video digital material again to create and display the class window tab. Since this method can cause significant inconvenience during the class, to solve this, the class window tab sync unit (40l) can sync the tab with another terminal in real time. When the class window tab to be used for the class is not distributed to some student terminals, disappears from a specific student terminal, or is terminated by a specific user, the class window tab to be used for the class can be restored to the student terminal where the class window tab to be used for the class has disappeared, and the class window tab identical to the class window tab created and displayed on the class window of another student terminal can be maintained in real time.

[0112] As described above, by performing the function of restoring the same class window tab as the class window tab created and displayed in the class window of another student terminal, this is referred to as the class window tab sync unit (40l) in the present invention.

[0113] In Korean Patent Publication No. 10-2025-0016787, detecting whether an educational screen has been arbitrarily terminated on some student terminal screens among multiple student terminals ((0057)), and if the educational screen is arbitrarily terminated, redistributing the configuration of the educational screen from the teacher terminal, and redistributing content including files and rules corresponding to the educational screen only to the terminated student terminals ((0056), (0248)), there is a problem in that when a problem occurs in the classroom environment of the student terminals, the teacher cannot identify which student terminal has the problem, and in order to redistribute the screen being taught to a specific student, the teacher can only find out if the student with the problem tells them.

[0114] To solve this, the class window tab sync unit (40l) according to the present invention does not need to identify what problem the student has, and can create a class environment where the class environment of the student terminal is automatically synced to be the same as that of other students while the teacher focuses on the class, thus having a completely different feature from Korean Patent Publication No. 10-2025-0016787.

[0115] The class and student management device (130) described in Korean Patent Publication No. 10-2023-0155814 is described as performing actions such as screen sharing of a specific student or all students, locking the screen of a student who cannot concentrate on the class, and tapping the screen through the look menu, but this does not restore the student class environment, nor does it synchronize the class environment with other students. This is a function intended to give students a warning, not to restore the class environment or prevent students from viewing other class content due to accidental touches. The class window tab synchronization unit (40l) according to the present invention is completely different from Korean Patent Publication No. 10-2023-0155814, and the class window tab synchronization unit is a function that quickly establishes the class environment at school.

[0116] In order for the class window tab sync unit (40l) to operate in the present invention, it is characterized by further including an identical class window tab check unit (40m) that checks in real time whether the class window tab (71-1) displayed on other student terminals (71) is displayed identically on the student terminal (72).

[0117] It is preferable to have the class window tab sync unit (40l) automatically activated through the same class window tab check unit (40m), but depending on the case, the class window tab sync unit (40l) may be activated by selecting a specific key or specific function in the first program (30) for the teacher terminal, and in the present invention, 'specific key or specific function' refers to a button that performs a specific function such as class start mode, class focus mode, tab focus mode, etc.

[0118] In addition, the present invention further includes a class window tab departure prevention unit (40a) configured in the second program (31) for the student terminal, wherein a class window tab corresponding to various digital class information received from the composite digital transmission unit (33) of the first program (30) for the teacher terminal is configured in the class window, and performs a function of drawing attention to a specific class window tab of the student terminal according to the class content when a class is conducted with the configured class window tab.

[0119] To explain the above-mentioned class window tab exit prevention unit (40a) as an example, when a class is being conducted using the video digital class window tab and the AI ​​courseware cahot class window tab, and the students are solving problems using the AI ​​courseware cahot class, the other class window tab is prevented from being used, so that all students participating in the class can only do the AI ​​courseware cahot class.

[0120] In other words, students can only view the specific class window tab desired by the teacher, and they cannot delete the class window tab or switch to another tab, allowing them to focus solely on the class window tab. This function of drawing attention to a specific class window tab is performed by the command of the information list section (53) and the information list control section (40e) configured in the tab management section of the teacher's terminal.

[0121] In this invention, the term "attention" is used because when a teacher selects one of at least one class window tab displayed on a plurality of student terminal screens from the class window tab information list on the teacher terminal, students can view only the educational screen corresponding to the selected class window tab on the teacher terminal; that is, by focusing on this, they cannot view or select the educational screens corresponding to other class window tabs, thereby causing them to focus on the class.

[0122] In addition, the present invention is characterized by further including a class window tab login unit (51) configured in the second program (31) for the student terminal, wherein a class window tab corresponding to various digital class information received from the composite digital transmission unit (33) of the first program (30) for the teacher terminal is configured in the class window, and when a web requiring a login is executed in a specific configured class window tab, the class window tab login unit receives necessary information from the terminal information unit configured in the student terminal and executes a login.

[0123] To explain the above class window tab login section (51) as an example, when conducting a class with the video digital class window tab and the AI ​​courseware Kahot class window tab, the AI ​​courseware Kahot class has a complex process in which you must take a picture of the QR code with the camera function of a laptop or Android device to enter the corresponding room number in order to conduct the class, and then enter a nickname to complete the entry into the room, so it is very difficult to start the Kahot class.

[0124] Of course, if there is only one student, it can be guided kindly, but if there are about 30 students, it is very difficult in reality to conduct regular classes within the given class time and then teach Kahot in the remaining time using this teaching method.

[0125] The class window tab login unit (51) according to the present invention, for solving such problems, solves the problem by automatically logging in on the class window tab by receiving necessary information from the login information stored in the class window tab login unit (51) of each student terminal (20), without the process of scanning a QR code and entering a room number or user nickname.

[0126] The first program (30) for a teacher terminal of the present invention further includes a class window tab management unit (40) configured in the first program (30) for a teacher to control a plurality of various class window tabs created and displayed in the class windows of a plurality of student terminals by receiving various class window tab information created and displayed in the student terminal from the class window tab management unit (40) configured in the second program (31) for a student terminal, and

[0127] The class window tab management unit (40) configured in the first program (30) for the teacher terminal above records information on class window tabs received from the class window tab management unit (40) of the multiple student terminals (20) to control multiple class window tabs (60) created and displayed in the class windows of multiple student terminals, and commands used to manage and control the class window tabs of the student terminals using the recorded information are registered, and the above commands include an information list control unit (40e) in which various commands such as close, focus, and release focus exist.

[0128] The above information list section (53) allows the teacher terminal (10) to check which of the at least one class window tab (60) displayed on the student terminal screen the student has displayed on the screen, and also, when the above information list section (53) is selected on the teacher terminal, an educational screen showing the class window tabs displayed on multiple student terminal screens is displayed on the teacher terminal.

[0129] The present invention further comprises a class window tab management unit (40) configured in a first program (30) for a teacher terminal that receives class window tab information generated and displayed in the second program (31) for a student terminal, and the class window tab management unit (40) configured in the second program (31) for a student terminal generates and displays class window tabs corresponding to various digital materials received from the composite digital transmission unit (33) configured in the second program (31) for a student terminal.

[0130] In the present invention, when a teacher selects and transmits PDF digital data, the composite digital transmission unit (33) transmits the registered PDF digital data using a data transmission method composed of socket communication or protocols such as UDP, MDNS, and FTP. The PDF digital data is then received by a plurality of second programs (31) for student terminals connected to the first program (30) for teacher terminals via the said communication method. The received PDF digital data is analyzed by the class window tab management unit (40) configured in the second program (31) for student terminals to determine if it is PDF digital data, and a class window tab for PDF classes is created and displayed in the class window of the student terminal.

[0131] Additionally, when a teacher selects and intends to transmit the AI ​​courseware product Tinkerbell, the composite digital transmission unit transmits the digital data using a data transmission method composed of socket communication or protocols such as UDP, MDNS, and FTP. The AI ​​courseware product Tinkerbell data is then received by multiple second programs (31) for student terminals connected to the first program (30) for teacher terminals via the aforementioned communication method. The received AI courseware product Tinkerbell data is analyzed by the class window tab management unit (40) configured in the second program (31) for student terminals to determine if it is the AI ​​courseware product Tinkerbell data, and an AI courseware product Tinkerbell class window tab is created and displayed in the class window of the student terminal.

[0132] The class window tab management unit (40) of the present invention, after various digital materials are transmitted through the composite digital transmission unit (33) and various class window tabs are created and displayed in the class window of the student terminal, if new digital materials are transmitted to the student terminal (20) without ending the class, one additional class window tab is created and displayed in addition to the existing class window tabs.

[0133] The class window tab management unit (40) configured in the second program (31) for the student terminal of the present invention further includes a class window tab video processing unit (40k) that receives various digital class materials from the composite digital transmission unit (33), filters the materials if they are video materials, removes other links associated with the video, and generates only the single video necessary for the class to create and display the class window tab; and the class window tab video processing unit (40k) is configured such that when YouTube is searched in the first program (30) for the teacher terminal, the target video and various videos related to the target video appear together according to the search results. At this time, when the teacher transmits the target video that appears according to the search results to the student terminal through the composite digital transmission unit (33), the class window tab video processing unit (40k) of the class window tab management unit (40) configured in the student terminal (20) filters the video so that only the target video of the video appears in the class window tab.

[0134] At this time, if only the intended video is filtered, it violates security according to YouTube's video playback rules, and the error code displayed is Video Playback Error 153. Therefore, it is difficult to fundamentally resolve Video Playback Error 153 easily. Since this invention is used by students in a school environment, it resolves the error to prevent link videos and advertisement videos other than educational videos from being included, and this was resolved because such a function must be an essential function.

[0135] In addition, the present invention further includes a class window tab departure prevention unit (40a) in which at least one class window tab displayed on a plurality of student terminal screens is displayed as an information list in a first program (30) for a teacher terminal, and when one class window tab information is selected from the information list of the first program for a teacher terminal, other class window tabs that do not match the class window tab selected from the information list are not displayed on the student terminal screen or are not selected.

[0136] In addition, the above-mentioned class window tab departure prevention unit (40a) ensures that when focusing on a specific class window tab of a student terminal, if the corresponding class window tab does not exist, the specific class window tab is synced and restored by the class window tab sync unit of the student terminal, and then the student focuses on the corresponding class window tab.

[0137] Looking at Korean Patent Publication No. 10-2484251, it is described that an administrator can monitor a remote monitoring screen (730) for a specific user terminal (110) through a video conferencing interface (700b) and collectively control blocking information for users participating in the video conference through a blocking program list (740) ((0110)). Looking at the class and student management device (130) of Korean Patent Publication No. 10-2023-0155814, it is described that actions such as screen sharing for a specific student or all students, locking the screen of a student who cannot concentrate on the class, and tapping the screen can be performed through the viewing menu ((0081)). Korean Patent Publication No. 10-2484251 describes collectively controlling blocking information for users participating in the video conference, which is a function that restricts specific remarks in the video conference and is completely different from the class window tab departure prevention unit (40a) of the present invention. The class window tab departure prevention unit (40a) of the present invention allows only a specific class window tab to be used among a plurality of class window tabs created as a class environment, and by using only a specific class window tab, it prevents students from making incorrect touches or incorrect malfunctions in advance, thereby maximizing the effectiveness of the class.

[0138] Korean Patent Publication No. 10-2023-0155814 describes a function for screen sharing, screen locking, and screen tapping through the look menu, which is a function for controlling the screen itself and not a function for controlling the student terminal. The class window tab departure prevention unit (40a) of the present invention is an environment for conducting classes using the class window tab of the student terminal, and the concept of screen tapping is a teaching method that encourages focus on the video by making a loud sound or highlighting the screen image with a color such as red when tapping the screen in a video conference. Therefore, it can be seen that this is completely different from the class window tab departure prevention unit (40a) of the present invention.

[0139] Additionally, the method further includes a class window tab deletion unit (40b) in which at least one class window tab displayed on a plurality of student terminal screens is displayed as an information list in the first program for the teacher terminal, and when any one class window tab information is selected from the information list of the first program for the teacher terminal (30), the class window tab matching the class window tab selected on the teacher terminal is deleted from the student terminal screen.

[0140] In addition, the present invention further includes a terminal-specific class window tab management unit (40g) that records and controls information of an educational screen in real time in which one or more class window tabs are displayed on each student terminal screen.

[0141] In addition, the present invention further includes an integrated class window tab management unit (40h) that records and controls information of an educational screen in real time, in which one or more class window tabs are displayed on a plurality of student terminal screens.

[0142] In addition, the class window tab management unit (40) configured in the second program (31) for student terminals controls the class window tabs for each terminal by recording in real time information of the educational screen in which one or more class window tabs are displayed on each student terminal screen, and the class window tab management unit (40) configured in the first program (30) for teacher terminals controls the integrated class window tabs by recording in real time information of the educational screen in which one or more class window tabs are displayed on multiple student terminal screens.

[0143] Initiating a monitoring event according to the execution of the conference program of Korean Registered Patent Publication No. 10-2484251 ((0012)), receiving and storing logs regarding transmission and reception packets and internal processes from a user terminal according to the initiation event ((0016)), providing a remote monitoring function for at least one user terminal to an administrator terminal ((0018)), and allowing the administrator to monitor a remote monitoring screen (730) for a specific user terminal (110) through a video conference interface (700b), and collectively controlling blocking information for users participating in the video conference through a blocking program list (740) ((0110)) are descriptions of general functions for conducting a video conference, and controlling the user's video screen does not mean controlling the local environment of the users participating in the video conference. The video conference system is related to controlling the videos participating in the video conference, and through this, it can be seen that it is completely different from the class window tab management unit (40) of the present invention, which controls student terminals in a school class environment.

[0144] Controlling users through a video conferencing system is controlled within the video conferencing program, but developing a class window tab management unit (40) through this would require more advanced thinking and skilled technology.

[0145] The class and student management device (130) described in Korean Patent Publication No. 10-2023-0155814 is described as performing actions such as screen sharing of a specific student or all students, locking the screen of a student who cannot concentrate on the class, and tapping the screen through the viewing menu. However, this is a simple screen lock and screen tapping to make the user concentrate on the video screen and block the video screen so that they cannot watch the video, and it does not control the user's local terminal, so the scope of development is completely different from the present invention.

[0146] Therefore, the class window tab management unit (40) according to the present invention is a technology for controlling student terminals in a school class environment, and is a method used in an environment where a teacher and students gather in one place to conduct a class.

[0147] The above integrated class window tab management unit (40h) further includes a class window tab analysis unit (40i) that receives multiple class window tab information from a class window tab management unit (40g) for each terminal that receives information of an educational screen in real time in which one or more class window tabs are displayed on each student terminal screen and records information for each terminal, and analyzes each of the received information to remove duplicate data and update it with newly merged information; and the above integrated class window tab management unit (40h) includes a tab list unit newly merged through the class window tab analysis unit (40i), and may enable the centralized deletion and control of multiple student terminals in an integrated manner at once.

[0148] In addition, the integrated class window tab management unit (40h) can integrate the tab list information of multiple student terminals so that all student terminals can synchronize with other student terminals to maintain the class window tab environment.

[0149] In the present invention, the information list, class window tab departure prevention unit, class window tab deletion unit, class window tab duplication check unit, class window tab restoration unit, information list control unit, tab list unit, class window tab management unit per terminal, integrated class window tab management unit, class window tab analysis unit, class mode unit, class window tab image processing unit, class window tab sync unit, class window tab login unit, terminal information unit, information list unit, etc., are preferably configured within the class window tab management unit or within the control unit of the present invention, but depending on the case, they may be configured separately without being configured within the class window tab management unit or the control unit.
